RSC Energia: Progress MS-02 logistics spacecraft launched to the ISS

March 31, 2016

Launch vehicle Soyuz-2.1a carrying a new-model logistics spacecraft Progress MS-02 was launched from Area 31 of the Baikonur launch site at 19:23:57 Moscow Time.

The spacecraft separated from the third stage of the launch vehicle normally at the expected time in its target orbit, after which the spacecraft set out on a free flight to the International Space Station. The spacecraft is scheduled to dock to the docking port on the propulsion compartment of Zvezda Service Module of the ISS Russian Segment on April 2, 2016 at 21:00:53 Moscow Time during its 34th orbit.

Progress MS-02 is to deliver to the station 1419 kg of dry cargo, 540 kg of propellant in the the refueling system tanks, 420 kg of water in the Rodnik system tanks, as well as 47 kg of compressed gases (air and oxygen) in canisters. The spacecraft launch mass was 7285 kg.

Stowed in the cargo compartment are equipment, components and consumables for various station systems, including medical and sanitary-hygienic supplies, containers with food rations, fresh food kits, a fire extinguisher, a storage battery, onboard documentation packages, as well as station maintenance and repair kits. The payload package includes instrumentation and consumables for geophysical and biomedical research and experiments in space biotechnology. The crew support items that are being delivered include parcels for the crew and letter stamps for special stamp cancellation marking the 55th Anniversary of the First Manned Space Mission and 70th Anniversary of RSC Energia. The spacecraft also carries 94 kg of US cargoes.

The logistics spacecraft will deliver to the ISS a microsatellite TOMSK-TPU-120, which is to be launched during a spacewalk. The satellite is a small but fully functional spacecraft with solar arrays, batteries, onboard radio equipment and other scientific instruments. A special feature of the microsatellite is that its body was printed on a 3D-printer. The main mission of the satellite is educational, it was developed by Tomsk Polytechnic University, with which RSC Energia cooperates within the framework of a strategic partnership agreement.

The new-series transportation spacecraft Progress MS and Soyuz MS were developed as a result of a radical upgrade of Progress M and Soyuz TMA spacecraft.

The onboard command radio system Kvant-B was replaced with an integrated command and telemetry system with an additional telemetry channel. The new command radio link makes it possible to receive signals via relay satellites Luch-5, which significantly increases the radio coverage zone for the spacecraft – up to 70% of an orbit.

The new-model spacecraft are equipped with an advanced onboard radio system for rendezvous and docking Kurs-NA. As compared with an earlier model, Kurs-A, it has improved mass and dimensions parameters and makes it possible to delete from the spacecraft hardware configuration one of the three radio antennas.

Instead of the analog TV system Klyost, the spacecraft use a digital TV system, which makes it possible to maintain communications between the spacecraft and the station via a space-to-space RF link.

Replacing the obsolete onboard hardware that is being phased out of production, the Soyuz MS and Progress MS models include in their hardware configuration: a new Digital Backup Loop Control Unit BURK developed by RSC Energia, an upgraded Rate Sensor Unit BDUS-3A and a LED headlight SFOK.

Thanks to the use of new ground and onboard radio systems, it became possible to use state-of-the-art data transmission protocols, which resulted in improved operational stability of spacecraft control system.

Most of the engineering solutions incorporated into the design of Soyuz MS and Progress MS spacecraft will be used in the design of the new-generation Crew Transportation Spacecraft (CTS), which is currently under development at RSC Energia.

 

OAO RSC Energia is the leader in the rocket and space industry, and the prime contractor for manned space systems. The Corporation conducts work on the development of unmanned space and rocket systems (launch vehicles and orbital transfer vehicles), and high-technology systems for various non-space applications. Since August 2014, the Corporation is headed by Vladimir Solntsev.
